This Standard describes the ATSC Non-Real-Time Content Delivery system, hereafter referred to as the ATSC NRT system or simply NRT. The NRT system provides support for delivery of content in advance of use (i.e., not streaming content). These ATSC-NRT services are carried in DTV broadcast multiplexes. The presence of these services do not preclude or prevent operation of current ATSC services in the same RF channel or have any adverse impact on legacy receiving equipment.
Schema files are located in the ATSC XML Schemas folder.
